Forte de ses missions brillamment r\u00e9ussies \u00e0 destination de Mars, V\u00e9nus et Titan, l\u2019Europe va maintenant explorer Mercure, la plan\u00e8te la plus proche du Soleil.<\/p>\n<\/div>\n

Nomm\u00e9e en l'honneur d'un c\u00e9l\u00e8bre math\u00e9maticien italien qui a \u00e9tudi\u00e9 la meilleure trajectoire vers Mercure, BepiColombo sera l'une des missions spatiales les plus complexes jamais r\u00e9alis\u00e9es. Trois modules seront lanc\u00e9s vers la plus petite plan\u00e8te du syst\u00e8me solaire : un orbiteur europ\u00e9en, un orbiteur japonais et un module de propulsion qui acheminera les deux engins spatiaux jusqu'\u00e0 Mercure.<\/p>\n

Pourquoi Mercure ? \u00c0 ce jour, seules deux sondes ont visit\u00e9 cette plan\u00e8te dont bonne partie de la surface doit encore \u00eatre examin\u00e9e en d\u00e9tail. Les questions rest\u00e9es en suspens auxquelles BepiColombo devra r\u00e9pondre sont nombreuses : Pourquoi Mercure est-elle principalement compos\u00e9e de fer ? Pourquoi cette plan\u00e8te a-t-elle un champ magn\u00e9tique ? Y a-t-il de la glace dans les crat\u00e8res ombrag\u00e9s et froids qui jouxtent ses p\u00f4les ? etc.<\/p>\n

L\u2019orbiteur MPO (Mercury Planetary Orbiter) de l\u2019ESA sera \u00e9quip\u00e9 de 11 instruments. \u00c9voluant en orbite polaire, il r\u00e9alisera une cartographie de la surface de la plan\u00e8te, recueillera des donn\u00e9es sur sa composition, en analysera les roches et \u00e9tudiera sa mince atmosph\u00e8re. L\u2019orbiteur japonais MMO (Mercury Magnetospheric Orbiter) se consacrera pour sa part \u00e0 l\u2019\u00e9tude du champ magn\u00e9tique de Mercure gr\u00e2ce \u00e0 ses cinq instruments de bord.<\/p>\n

BepiColombo sera la premi\u00e8re mission vers cette plan\u00e8te myst\u00e9rieuse \u00e0 \u00eatre compos\u00e9e de deux orbiteurs. Le lancement devrait avoir lieu au mois de juille 2016. Apr\u00e8s un long voyage en spirale \u00e0 travers le syst\u00e8me solaire interne, BepiColombo atteindra sa destination en 2024.<\/p>","protected":false},"excerpt":{"rendered":"
